Ryan C. Gordon If you have the X11 SDK installed on Mac OS X, you'll build with X11 support, but the Makefile doesn't build anything but the Cocoa testnative code for Mac OS X, which is fine, but then testnative fails to link because testnative.h enables the X11 support based on the SDL config header. Building the testnativex11.c code on Mac OS X doesn't work because you need to explicitly link with "-L/usr/X11/lib -lX11" if this code is enabled, but you can't link with that by default because the X11 SDK might be missing. So this needs a little configure magic to do the right thing (or forcibly disabling X11 support on Mac OS X in testnative.h).
